STEVENAGE, England -- Surrogate mother Carole
Horlock, 42, has delivered 12 babies in 13 years, including
triplets last March-setting the world record for the Most
prolific surrogate mother.Carole Horlock: "When I first
started being a surrogate I expected to do it once," she said.
"I hadn't looked past that. But I enjoyed it so much. Before
I actually had given birth to the baby I wanted to do it again."

She told the ABC News program "20/20."
: "When I first started being a surrogate I expected to do
it once," she said. "I hadn't looked past that. But I enjoyed
it so much. Before I actually had given birth to the baby
I wanted to do it again."

Surrogates receive an average $25,000 to $30,000
for their services, "20/20" said.

Carole Horlock has parlayed
her extreme surrogate status into additional profit by selling
her story to tabloids newspapers.

But sometimes the headlines have turned
nasty, she said.

"You do it once or twice and you're an
angel. You do it time and time again, you're a monster," she
said. "If it's a good deed the first time, why doesn't it
continue being a good deed?"

Horlock will make no demands on the parents
of the triplets beyond requesting an annual letter and photograph
to let her know how they are doing.

But her surrogacy experiences have not
all been positive. Her father rarely speaks to her, distressed
that she is effectively giving away his grandchildren.

She said she finds satisfaction in surrogacy.

"Some people are scientists, they are working
toward a cure for cancer or they made the first airplane,"
she said. "But you know, at the end of
my life, I can look back and say, you know, I made a difference
to these people."
